Abstract
A light source installation in back light unit to effectively shorten the area required for incorporation of wavelength from each of multiple LEDs is comprised of multiple LED units; each LED unit being comprised of multiple LEDs; multiple LED units being disposed on a locking member and each LED unit being disposed on a curved section formed by the locking member and further on the incident plane of the light guide plate in different directions; and light emitted from those multiple LED units being mixed to incorporate wave length from each LED into white light.
Claims
exact text as granted — not AI-modified1 . A light source installation in back light unit to effectively shorten the area required for incorporation of wavelength from each of multiple LEDs is comprised of multiple LED units; each LED unit being comprised of multiple LEDs;
each LED unit being disposed in various directions on the incidence plane of a light guide plate; and wave length of each LED being incorporated into white light due to light mixing.
2 . The light source installation in back light unit as claimed in claim 1 , wherein the light source installation is adapted in a reflective mask.
3 . The light source installation in back light unit as claimed in claim 1 , wherein the light source installation is applied in a back light unit; a reflective mask being disposed on the edge of a display panel assembly of the back light unit;
and the light source installation being adapted in the reflective mask.
4 . The light source installation in back light unit as claimed in claim 2 , wherein those multiple LEDs are disposed on the reflective mask in different directions.
5 . The light source installation in back light unit as claimed in claim 3 , wherein those multiple LEDs are disposed on the reflective mask in different directions.
6 . The light source installation in back light unit as claimed in claim 3 , wherein the display panel assembly includes light guide plate, lower diffusion film, brightness enforcement film, upper diffusion film, and LCD panel.
7 . The light source installation in back light unit as claimed in claim 1 , wherein the light guide includes an incidence plane, a base plane crossing the incidence plane, and an emitting plan in opposite to the base plane.
8 . The light source installation in back light unit as claimed in claim 4 , wherein a reflective film is further disposed below the base plane of the light guide plate.
9 . The light source installation in back light unit as claimed in claim 5 , wherein a reflective film is further disposed below the base plane of the light guide plate.
10 . A light source installation in back light unit to effectively shorten the area required for incorporation of wavelength from each of multiple LEDs is comprised of multiple LED units; each LED unit being comprised of multiple LEDs;
multiple LED units being disposed on a locking member and each LED unit being disposed on a curved section formed by the locking member and further on the incident plane of the light guide plate in different directions; and light emitted from those multiple LED units being mixed to incorporate wave length from each LED into white light.
11 . The light source installation in back light unit as claimed in claim 10 , wherein the locking member related to a reflective mask.Cited by (0)
